Martin, 17, was killed while walking to his father's fiancee's house in Sanford from a nearby convenience store.

Zimmerman first called police atĀ 7:09 p.m. ET with concerns about a suspicious teen in the area, according to 911 tapes released by the Seminole County Sheriff's Department.

A 16-year-old girl who was on the phone with Martin most of the day last spoke to him around the time the incident allegedly began and lasted until 7:16 p.m. ET, when the call dropped. Almost immediately, 911 calls began coming in.Ā Ā Police arrived on the scene at 7:17 p.m.

Several witnesses called 911 at 7:16, 7:17, 7:18 and 7:19 p.m. ET.

Below are the transcripts of the calls as Zimmerman and witnesses describe what they saw and heard that night:

7:09 p.m. ET

Dispatcher: "Do you need police, fire or medical?"

Zimmerman: "We had some break-ins in our neighborhood ... and there is a realĀ suspiciousĀ guy. ... This guy looks like he's up to no good, he's on drugs or something. It's raining, and he's walking around looking about. "

Dispatcher: "Is this guy white, black,Ā Hispanic?"

Zimmerman: "He looks black."

Dispatcher: "Did you see what he's wearing?"

Zimmerman: "A dark hoodie, grey hoodie, jeans or sweatpants or white shoes. He's walking around staring at the houses. Now he's just staring at me."

Dispatcher: "Location?"

Zimmerman: "He's near the clubhouse right now. Now he's coming towards me. He has his hands in hisĀ waistband. He is a black male. Something's wrong with him. Yep. He's coming to check me out. He's got something in his hands. I don't know what his deal is. Send officers over here."

Dispatcher: "Let me know if he does anything else."

Zimmerman: "These a**holes, they always get away. When you come in go straight to the left ... when you pass the clubhouse ..."

Zimmerman: "Tell them to come past the clubhouse and make a left then past mailboxes and they will see my truck ..."

Dispatcher: "What's your apartment number?"

Zimmerman: "It's a home. ... IĀ don'tĀ want to give that out. I don't know who this kid is."

Dispatcher: "I will let them know where to meet you."

Zimmerman: "Have them call me, and I will let you know where I'm at."

During part of this time, Martin is on the phone with a 16-year-old girl. Below is an account of the phone call as relayed to In Session's Sunny Hostin by a lawyer for the Martin family:

Martin told the girlĀ someone was following him, and she advised him to run. Martin said he isn't going to run but will walk quickly. Zimmerman caught up with him, and Martin asked Zimmerman why he was following him. Zimmerman then asked Martin his name and why he was there. The girl on the phone says she heard Zimmerman push Martin, and then the call drops. She tried to call Martin back, but he didn't respond.

Caller: "No, I don't because I'm hiding upstairs. The gunshot was outside our house. You sent somebody, right?"

Dispatcher: "Do you hear any vehicles leaving or anything else?

Caller: "There's people yelling down there, but I don't want to go down there."

Dispatcher: "People are yelling now?"

Caller: "Yeah."

Dispatcher: "We do have officers on the way. Call us back if you see any vehicles leaving or anything."

As far as you know, it's coming from behind your house near yourĀ back-porchĀ area? When you hear screaming, was it screaming of female or male?"

Caller: "Male."

Dispatcher: "So, when you heard screaming, it was a male screaming?"

Caller: "Yes. And the guy on top had a white t-shirt."

Dispatcher: "What do you mean guy on top? Did you see a fight?"

Caller: "IĀ don'tĀ know, I just looked out my window, and there was a guy on top wearing a white t-shirt."

Dispatcher: "Listen, we don't know if they been killed ..."

Caller: "Yes, the person is dead, laying on the ground."

Caller: "I didn't see cause it was too dark, and I just heard people screaming 'help me, help me.' And this person shot him! He was like wrestling with him, you know what I mean, on the ground, from what I can see it was very dark. The man didn't try to run away or anything. I don't want to be a witness or anything.

Dispatcher: "Did you see or hear anything else like a vehicle pulling away?"

Caller: "No, ma'am, because I'm in the back, and in the back there is just a walkway. It could have been someone in the front with a car, I don't know, but I was in the back. It was scary. There is someone still back there with flashlights walking around."

Officers arrived on the scene at 7:17 p.m. ET, according to a police report.

Officers Timothy Smith and Ricardo Alayo said they noted a black male in a gray hooded sweatshirt lying face-down in the grass, as well as a white male in the area.

"Zimmerman stated that he had shot the subject and was still armed," Smith wrote in a police report.

Smith said he asked Zimmerman to hand over the weapon, a Kel Tec 9 mm, and handcuffed him.

"While I was in such close contact with Zimmerman, I could observe that his back appeared to be wet and he was covered in grass, as if he was laying on his back on the ground," Smith wrote in the police report. "Zimmerman was also bleeding from the nose and the back of the head."

The officers also made several attempts to revive Martin.

When police put Zimmerman in the back of the cruiser, he said, "I was yelling for someone to help me, but no one would help me," according to the police report.

THe kid George Z is white and Hispanic. Many white Hispanics are racist. Who do you think discovered AMerica and brought the very first black slaves into the New World? SPAIN!!! Over 100 yrs before the UK came to the Americas.

Self defense??? why was this guy following the young boy when he was ordered not to follow? What this guy thought he was? a hero? If someone is chasing me I would do the same thing that poor guy maybe did – fight back!. That was not self defense – that was killing someone who was scared. I hope he rots in jail

Layla, so quick to blame this on race... can't you just move forward. Do you really think he shot him because he's black? What if he was white? would you even post? probably not... continue whining and wasting time

Funny how people already made up their minds, saying the "kid" was yelling for help when they heard the shot. Funny how zimmerman had a bloody nose and was bleeding from the back of the head and stated he was yelling for help. funny how the media shows a pic of a little boy in a football uniform. Something it's terribly wrong in this country when the media does not report facts, but reports biased and one-sided stories. Funny, because I've seen it before. Someone smells money, and the liberal media smells blood because they've turned into drama and racially motivated "tragedy". cnnsukz.

When Zimmerman pulled out a gun (clearly fearful of a paper cup of beverage as a weapon), there may well have been an altercation resulting in some blood on Zimmerman. But as the kid wasn't armed, how could it have been self-defense?

funny how Mr Z chased the kid! If you were to try to chase my wife down just to ask her what's she "doing here", God help you because she is going to pull out a pink 9 mm and shoot you! Here in TX we have CC and Castle Law as well and running after someone is percieved as a threat

Exactly, they put up an insidious "mugshot" style picture of Zimmerman, and then plaster a collage of childhood pictures of Martin.....this was my first clue that something was clearly up with this whole story. CNN is easily the most dishonest media outfit on television.

It seems that Zimmerman was the one yelling "help". When he got in the police care right after the incident he said "i was yelling for help". Unlikley he would make that up considering his emotional state at the time.

Hey John, guns don't kill people. People kill people. Peopel are killled by cars that are driven by people every day- should we outlaw cars? If guns were banned, only criminals would have guns. Guns have more than one purpse....one of them is to defend and another one is to deter violence. Leave our Bill of Rights alone and take some fire arm training and learn the law.

I would not fault this kid if it is discovered that he fought with this weirdo guy. With all of the pervs out here today...who knows what he thought Zimmerman was thinking of possibly doing to him...following him like that especially since he hadn't done anything wrong! Zimmerman didn't have on any identifying clothing to suggest he was a law officer...that's right he was not...why would Trayvon not defend himself?
